GLOBAL URANIUM CORP. ANNOUNCES COMPLETION OF GEOLOGICAL MAPPING AT THE AIRLINE PROJECT IN WYOMING

Global Uranium Corp. has completed detailed geological mapping at the Airline project in the Wind River basin of central Wyoming. The mapping program represents the first component of the 2025 field program at Airline, which also included a radiometric survey, as well as hand samples for geochemical assay and mineralogical analysis. The results of those additional data sets will be reported as they become available.

The mapping was completed over one week by Big Rock Exploration in late October, 2025, and improved the company's understanding of stratigraphy and structure at Airline. Multiple key geological units were validated across the study area. The Tertiary Wagon Bed formation was confirmed to be widespread, displaying characteristic tuffaceous sandstones, interbedded tuffs, and granola- or popcorn-style weathering textures. Archean crystalline basement was mapped in several locations, including granite and monzogranite with abundant pegmatitic dikes, deep weathering and bleaching near the overlying unconformity. Several flathead sandstone outcrops were identified on the western side of the study area. The contact between the Wagon Bed formation and the Archean basement was mapped in several locations and remains one of the most important stratigraphic targets on the property, as earlier radiometric anomalies appear to originate close to this unconformity. Mapping also documented several arkosic sandstone outcrops that share similarities with the Wind River formation, including porous textures and local iron-oxide nodules.

Two priority horizons have emerged from the fieldwork. The first is the unconformity between the Wagon Bed formation and the Archean granite, where anomalous radioactivity, bleaching and clay alteration were documented. The second is a discrete arkosic sandstone horizon informally referred to as the Scorpion unit, where radiometric highs coincide with favourable textures and local structures. All accessible rocks on the property were oxidized to varying degrees and no reduced ground was encountered. Several hand samples collected near the unconformity displayed intense clay alteration, hematite replacing former pyrite crystals, and uranium-bearing minerals such as autunite and a possible occurrence of metatorbernite, which was visible under ultraviolet light. Mineralogical identification is pending thin-section work; no conclusions have been drawn regarding mineral origin or paragenesis at this stage.

The mapping data set will be integrated with the forthcoming ground-based radiometric grid, as well as geochemical assays and mineralogical results. A combined interpretation will support refined stratigraphic modelling and drill target development for 2026. Future fieldwork may include additional focused mapping in the eastern and northeastern parts of the property, where further exposures of the unconformity and arkosic sandstone units may refine the exploration model. Additional work is also suggested in the northwest of the project area, where orthophotos indicate further potential for contact zones between granites and Eocene sediments.

Ungad Chadda, chief executive officer of Global Uranium, commented: "This mapping program has strengthened our geological understanding of the Airline project and confirmed several important features that warrant further work. These results will play a meaningful role in refining our next steps and informing our broader exploration strategy."
